When the engine misfires, high concentrations of hydrocarbons (HC) enter the exhaust gas. Extremely high hydrocarbon concentration levels can
cause increases in exhaust emission levels. High concentrations of hydrocarbons can also cause increases in the three-way catalytic converter
temperature, which may cause damage to the three-way catalytic converter. To prevent these increases in emissions and to limit the possibility of
